Iran Warns of Response Without ‘Full Implementation’ of US Peace Deal

Iran’s Parliament Speaker Mohammad Bagher Ghalibaf on Friday warned of a response from Tehran if the United States and Israel breach an interim peace deal, as the Iranian regime prepares to bury its former top leader.

While he was meeting with an official from Belarus, Ghalibaf that Iran “will strongly demand full implementation of the agreements, and [if the United States and Israel] fail to fulfill their commitments, Iran will resume proportionate actions,” according to the semi-official Iranian Students’ News Agency (ISNA) media outlet.

He also claimed that the U.S. military wasn’t successful in its operation against the Iranian regime, alleging Washington “requested a ceasefire themselves.”

U.S. President Donald Trump and other administration officials, however, have said that Iran’s military capabilities were significantly denigrated by U.S. attacks on the country that started in February, while U.S. forces later imposed a naval blockade on the country’s ports for roughly two months.

Before a ceasefire in April, Trump warned that American forces could strike Iranian power plants, bridges, and other infrastructure.

Meanwhile, Iran was preparing on Friday for the funeral of the late top leader Ayatollah Ali Khamenei, with banners across Tehran urging the public to rise up in support of the Iranian regime after the devastating strikes that killed the 86-year-old leader and a number of other top leaders.

Video published by Iranian state media showed an earlier mourning ceremony for Khamenei on Thursday night. The black-clad mourners, whom state media identified as coming from families of those who lost loved ones in the 12-day war in 2025 and the recent Iran war, threw scarves and other items for attendants to brush against the coffin, a common practice in Iran.

Khamenei’s death has raised questions about the future of Iran. Khamenei’s son, Mojtaba Khamenei, was chosen as the next top leader. However, he was believed to have been wounded in the strikes that killed his father and has not been seen publicly since he was named to the position in mid-March.

As Trump launched the war, he called on Iranians to “take over your government.” There have been few signs yet of any such uprising, however, as hard-liners have rallied nightly in the streets of Tehran.

In January, thousands of Iranian demonstrators took to the streets to protest against the government and its economic policies, drawing a significant crackdown on dissent.

Beginning Saturday, Iran will hold a dayslong funeral for Khamenei, and his body will be transported to cities in Iran and neighboring Iraq. Authorities plan to shut down streets, airspace, and daily life in Tehran.

Earlier this week, the Trump administration held talks with an Iranian delegation in Qatar over points laid out in a memorandum of understanding to end hostilities for at least 60 days. The administration wants Iran to hand over or dilute enriched uranium, end its nuclear program, and allow for the reopening of the Strait of Hormuz, a key waterway that transports large portions of crude oil.
